I got the following problem when trying to make screw threads –
Helix within a sweep works fine when upright. When rotated 90° I get weird twists within the sweep.
When turning banking on the twists disappear, but my thread is getting thinner to the ends and thicker in the middle.
Maybe try making an instance of your helix and move the instance up a bit in the Y axis. The put the instance inside the sweep nurbs object as a rail, and turn of rail scale. That should keep your sweep in line without banking
